Pretty good job. It's annoying seeing people complain and chastise you about the filesize, and unfortunately thats probably the way its going to be for a while until people realize different files beyond .swfs can be uploaded to newgrounds.
Anyway, the modeling was pretty good. I think you animated the emotion nicely, but the face was a bit too cartoony to take seriously. Not because you didn't do a good job, just the way it was proportioned. Music was very fitting, but some of the sounds, like the mouth opening, sighs, and gunshots were pretty awkward sounding. But other than that, good job man.
